A bit of Python basics. Day 2: merging dictionaries

If you have two dictionaries that need to be merged, this can be done in two simple ways. You can use the merge operator (|) or the operator (**). Below we have two dictionaries: first_dict and second_dict. We will use these two methods to merge the dictionaries. Here's the code:

1️⃣ Using the merge operator (|)

first_dict = {"kelly": 23,
              "Derick": 14, "John": 7}
second_dict = {"Ravi": 45, "Mpho": 67}

combined_dict = first_dict | second_dict
print(combined_dict)

Output:

{'kelly': 23, 'Derick': 14, 'John': 7, 'Ravi': 45, 'Mpho': 67}

2️⃣ Method 2: using the merge operator (**)

With this operator, you need to put the dictionaries inside curly braces. In the code below, we "substitute" two dictionaries for merging using two operators *. Both dictionaries are enclosed in curly braces and separated by a comma.

first_dict = {"kelly": 23,
              "Derick": 14, "John": 7}
second_dict = {"Ravi": 45, "Mpho": 67}

combined_dict = {**first_dict, **second_dict}
print(combined_dict)

Output:

{'kelly': 23, 'Derick': 14, 'John': 7, 'Ravi': 45, 'Mpho': 67>
